Judy Webster is born in a mud-splattered tent at Woodstock, just as Crosby, Stills, and Nash take the stage. Her mother, Cassie, is a beautiful, flawed flower-child who brings her little girl to anti-war protests and parties rather than enroll her in pre-school. But as Cassie's husband, Kirk, gradually abandons '60s ideals in favor of a steady home and a law degree, their once idyllic marriage crumbles.
When seven-year-old Bethany meets her six-year-old cousin Reana Mae, it's the beginning of a kinship of misfits that saves both from a bone-deep loneliness. Every summer, Bethany and her family leave Indianapolis for West Virginia's Coal River Valley. For Bethany's mother, the trips are a reminder of the coalmines and grinding poverty of her childhood, of a place she'd hoped to escape. But her loving relatives, and Bethany's friendship with Reana Mae, keep them coming back.
